也可在釜內(nèi)部安裝蛇管.夾套式換熱器***用于反應(yīng)過(guò)程的加熱和冷卻。沉浸式蛇管換熱器：這種換熱器是將金屬管彎繞成各種與容器相適應(yīng)的形狀，并沉浸在容器內(nèi)的液體中.蛇管換熱器的優(yōu)點(diǎn)是結(jié)構(gòu)簡(jiǎn)單，能承受高壓，可用耐腐蝕材料制造；其缺點(diǎn)是容器內(nèi)液體湍動(dòng)程度低，管外給熱系數(shù)小.為提高傳熱系數(shù)，容器內(nèi)可安裝攪拌器。噴淋式換熱器：這種換熱器是將換熱管成排地固定在鋼架上，熱流體在管內(nèi)流動(dòng)，冷卻水從上方噴淋裝置均勻淋下，故也稱噴淋式冷卻器.噴淋式換熱器的管外是一層湍動(dòng)程度較高的液膜，管外給熱系數(shù)較沉浸式增大很多.另外，這種換熱器大多放置在空氣流通之處，冷卻水的蒸發(fā)亦帶走一部分熱量,可起到降低冷卻水溫度，增大傳熱推動(dòng)力的作用.因此，和沉浸式相比，噴淋式換熱器的傳熱效果大有改善。套管式換熱器套管式換熱器是由直徑不同的直管制成的同心套管，并由U形彎頭連接而成.在這種換熱器中，一種流體走管內(nèi)，另一種流體走環(huán)隙，兩者皆可得到較高的流速，故傳熱系數(shù)較大.另外，在套管換熱器中，兩種流體可為純逆流，對(duì)數(shù)平均推動(dòng)力較大。套管換熱器結(jié)構(gòu)簡(jiǎn)單，能承受高壓，應(yīng)用亦方便(可根據(jù)需要增減管段數(shù)目).特別是由于套管換熱器同時(shí)具備傳熱系數(shù)大。浙江石化換熱器板式換熱器應(yīng)用案例有哪些？</p><div

宏觀上均勻的腐蝕破壞叫均勻腐蝕。接觸腐蝕兩種電位不同的金屬或合金互相接觸,并浸于電解質(zhì)溶解質(zhì)溶液中,它們之間就有電流通過(guò),電位正的金屬腐蝕速度降低,電位負(fù)的金屬腐蝕速度增加。選擇性腐蝕合金中某一元素由于腐蝕,優(yōu)先進(jìn)入介質(zhì)的現(xiàn)象稱為選擇性腐蝕?？孜g集中在金屬表面?zhèn)€別小點(diǎn)上深度較大的腐蝕稱為孔蝕,或稱小孔腐蝕、點(diǎn)蝕?？p隙腐蝕在金屬表面的縫隙和被覆蓋的部位會(huì)產(chǎn)生劇烈的縫隙腐蝕。沖刷腐蝕沖刷腐蝕是由于介質(zhì)和金屬表面之間的相對(duì)運(yùn)動(dòng)而使腐蝕過(guò)程加速的一種腐蝕。晶間腐蝕晶間腐蝕是優(yōu)先腐蝕金屬或合金的晶界和晶界附近區(qū)域,而晶粒本身腐蝕比較小的一種腐蝕。應(yīng)力腐蝕破裂()和腐蝕疲勞是在一定的金屬一介質(zhì)體系內(nèi),由于腐蝕和拉應(yīng)力的共同作用造成的材料斷裂。氫破壞金屬在電解質(zhì)溶液中,由于腐蝕、酸洗、陰極保護(hù)或電鍍,可以產(chǎn)生因滲氫而引起的破壞。3·冷卻介質(zhì)對(duì)金屬腐蝕的影響工業(yè)上使用**多的冷卻介質(zhì)是各種天然水。影響金屬腐蝕的因素很多,主要的幾個(gè)因素及其對(duì)幾種常用金屬的影響:溶解氧水中的溶解氧是參加陰極過(guò)程的氧化劑,因此它一般促進(jìn)腐蝕。當(dāng)水中氧的濃度不均勻時(shí),將形成氧的濃差電池,造成局部腐蝕。專業(yè)生產(chǎn)換熱器的廠家有哪些？陜西換熱器代理銷售價(jià)格</p><p
